A nurse is educating parents on the signs of suicidal ideation in adolescents. Which sign should the parents be most vigilant about due to its direct association with suicide risk?

A. Giving away personal belongings is a significant warning sign of suicidal ideation because it may indicate preparation for death and closure. Adolescents who are planning suicide sometimes distribute prized possessions as a way to say goodbye, making this behavior a direct and urgent indicator of risk. B. Decline in academic performance can be associated with depression or stress but is a nonspecific indicator. While concerning, it does not directly signal imminent suicide risk. C. Withdrawal from social activities is a common symptom of depression or social anxiety. Although it increases vulnerability and may correlate with suicidal ideation, it is not as direct a warning sign as giving away belongings. D. Frequent fatigue and headaches are physical symptoms that can accompany depression or stress but are not specific indicators of suicide risk.
